patients, 11 of whom had cholecystitis. Two major complica­tions (one stroke and one trocar herniation) and thirteen minor complications were reported (12.7%). Among the gynecologic complications, infection and dehiscence of the colpotomy closure were reported.
Discussion
Currently, transvaginal access is the preferred approach in humans because this route obviates the risk of intestinal content leakage via an imperfectly closed access site. Almost all reported procedures use some form of transparietal assist­ance for exposure of the gallbladder, application of laparo­scopic clips to seal the cystic duct, and assistance in visualization and dissection. The postoperative outcome is favorable in most of studies. Reported mortality rate is 0%. Biliary leaks were reported in four studies and treated suc­cessfully by laparoscopic or endoscopic drainage and stent­ing. Few gynecologic complications were reported. No clinical randomized trial comparing NOTES and laparoscopic cholecystectomy has ever been published. Results of multi­center trials have been recently published. In the Germany NOTES registry, the analysis was based on an anonymous and voluntary registry, having its inherent advantages and limitations [22]. In an update of the registry (oral presenta­tion 2010 Digestive Disease Week), Lehmann presented results on 1328 patients at 87 hospitals participating in the registry between March 2008 and September 2010. All but 10 of the patients in the registry were women. A transvagi­nal approach was used in 1310 of the operations, transgas­tric in 4, transrectal in 9, and another approach in 1. There were 26 conversions to laparoscopy and 12 to laparotomy. There were 22 intraoperative complications (1.6%), 34 post­operative ones (2.5%), and no deaths so far. The two major intraoperative complications were a rectal injury requiring a Hartmann procedure later and a small bowel injury neces­sitating segment resection. In addition to minor complica­tions in the postoperative period, there were two laparoscopies for pain (without pathological fi ndings) and one laparo­scopic drainage for an abscess in the pouch of Douglas. No biliary injury was reported. In an International Multicenter Trial reported by Zorron et al. [9], the intraoperative com­plication rate of transvaginal cholecystectomy (240 patients) was 6.6%, postoperative complications were observed in
8.1%. Bleeding from the cystic artery (fi ve patients), gastric and bowel injury (two patients), and vaginal laceration (three patients) were successfully managed intraoperatively. Biliary leak was observed in two patients, and was managed by nasobiliary and percutaneous drainage in one patient and laparoscopic re -operation in the other. These large reports demonstrate that transvaginal NOTES cholecystectomy can be performed safely.
Experience has shown that the use of a new access to perform a surgical procedure induces new complications. This was observed when laparoscopy was introduced, with the description of visceral and vascular injuries associated with the use of trocars. Given the low rate of access compli­cations, the transvaginal route compares favorably with laparoscopic access. The reported rate of procedure -related complications is also very low. Major bile tract injury has never been reported but we must bear in mind that the majority of operations were performed in selected patients, by dedicated teams under control of strict IRB protocols. With appropriate training, experience, and patient selection, the use of a hybrid transvaginal technique seems feasible and applicable to routine clinical use.
The major concern with the transgastric procedures is the safety of creation and closure of the gastrotomy. Laparo­scopic surveillance is used by few teams having limited experience. Liberal use of additional laparoscopic trocars is mandatory to overcome problems that are encountered at all steps of the procedure: access, retraction of the gallblad­der, dissection, clipping, and closure of the gastrotomy. An additional challenge is to obtain adequate spatial orientation with the endoscope in a retrofl exed position when the image is upside down and off -axis manipulation is required. Although some of this spatial incongruity is likely to be overcome with experience, exposure, interpretation of the anatomy, and identifi cation of the structural landmarks proved demanding [24]. The access -related complication rate is low, given that gastrotomy is performed under laparo­scopic surveillance. However, bleeding from epiploic vessels needed conversion to open surgery in one patient [9]. Bile leak was reported in 2 of 29 patients [9]. The experience reported in the literature is very limited and no conclusion can be drawn. TGC epitomizes the inadequacy of the current fl exible endoscope and instruments for performing NOTES procedures and must be considered very cautiously.
Conclusions
Currently, most cholecystectomies in the developed world are performed laparoscopically with excellent results; the bar has thus been set very high. The future of NOTES chole­cystectomy lies not only in the development of adequate technologies but also in the patient ’s perception of the potential advantages and risks of such an innovative approach. Both parameters are strongly linked, as there is no future for a technique that would be used in a minority of patients. Although NOTES is still evolving, studies dem­onstrate that a majority of patients perceive NOTES favora­bly as a potential technique for a cholecystectomy. This preference for NOTES diminished remarkably if the compli­cation rates were greater than that for a laparoscopic chole­cystectomy [25,26]. Procedure -related risks, pain, and

recovery time were more important than cosmesis, cost, length of hospital stay, and anesthesia type in the choice. Attempts at reducing cholecystectomy -associated morbidity and improving cosmesis are valuable and will drive the development of novel surgical instrumentation.

Introduction
Developments in surgical medicine during the late twentieth and early twenty -fi rst century are characterized by a con­stant reduction in the invasiveness of surgery while uphold­ing operative standards. In certain procedures, such as cholecystectomy and appendectomy, open surgery has gen­erally been superseded by laparascopic surgery. With other surgical procedures, such as colon resection, a large propor­tion of operations are performed laparoscopically.
In the case of other medical conditions, such as the treat­ment of complications arising with acute and chronic pan­creatitis, there has been a shift away from open surgery to interventional endoscopic and sonographic procedures.
After the fi rst reports concerning the accessing of the abdominal cavity via an external orifi ce and thence via an internal organ [1], natural orifi ce translumenal endoscopic surgery (NOTES) as a new surgical method involving the introduction of fl exible endoscopes into the abdominal cavity was initially used in animal experiments. Now that the move away from open surgery and toward the mini­mally invasive technique of laparoscopic surgery has taken place, endoscopic translumenal surgery represents the next stage in this cascade, with the need for abdominal incision being completely eliminated [2]. The anticipated benefi ts are a reduction in postoperative wound pain, shorter convales­cence, avoidance of wound infections and abdominal wall hernias, as well as the absence of scars [3–5]. In this tech­nique, the desired organ is accessed via a natural orifi ce.
In the operative treatment of acute appendicitis, laparo­scopic surgery can be regarded as the standard procedure [6]. However, the process of transition from open to laparo­scopic surgery has taken considerably longer than in the case of cholecystectomy. In addition to the cosmetic effect, which
is not particularly emphasized, the advantages of the lapara­scopic procedure are listed as shorter stays in hospital and a lower rate of wound infection [7,8]. A higher rate of post­operative intra -abdominal abscesses, which has occurred in isolated cases, cannot be generalized; it is dependent on primary peritoneal contamination [7,9]. Particularly in the analysis of subgroups such as overweight patients and atypi­cal positions of the appendix, laparoscopic surgery has led to a shortening of operating times and hospital stays, and, in the case of the fi rst group of patients, to a signifi cant reduction in the wound infection rate [10]. Initially expressed fears that the predominance of the laparoscopic appendectomy procedure would lead to the loss of a training operation have not been borne out [6,11].
With the introduction of NOTES techniques to appendec­tomy as a further step in reducing invasiveness, the said problems will have to be re -evaluated, but not until these technologies have fully matured and can be extensively employed. It is inevitable that, until the technique is fully developed, a basic operation will be in the hands of just a few specialists, but any new procedure can only become established if it can be employed on a broad scale.
Techniques of NOTES appendectomy
Initial historical and gynecologic appendectomies
Long before the inauguration of the term “NOTES” there were sporadic reports in the gynecologic literature concern­ing transvaginal resection of the appendix, always in con­nection with transvaginal gynecologic surgery.
The fi rst report of transvaginal appendectomies was pub­lished by Bueno in 1949 after performing the surgery on three patients [12]. These operations were performed during and after vaginal hysterectomy and extirpation of the

adnexa. In all cases, exposure of the appendix was only pos­sible after displacement of the intestines. The operations and patients’ postoperative progress were free of complications.
The fi rst series of ten transvaginal appendectomies was reported by McGowan in 1966 [13]. The operations were performed between 1958 and 1964. In two cases only a posterior colpotomy was performed to provide access; in the other cases the procedure was conducted following a hys­terectomy. The treatment was carried out in the conven­tional manner. All the appendectomies were prophylactic in character.
In 1975 Massoudnia reported 225 incidental appendecto­mies performed in connection with 2200 vaginal operations, hysterectomies, and colpotomies performed for other purposes [14]. The operating time was extended by an average of 15 minutes as a result of the appendectomy; no appendectomy-related complications occurred. A majority of the patients who had undergone colpotomy and appen­dectomy were discharged on the third day after surgery; the average hospital stay of all patients was eight days.
In connection with laparoscopically assisted hysterecto­mies, Pelosi and Pelosi report on 12 cases of vaginal inciden­tal appendectomy [15]. Preparatory laparoscopic exploration was regarded as useful for evaluating the mobility of the cecum and the appendix.
In the past, the procedure involved pulling the cecum into the vaginal cavity in order to remove the appendix.
The fi rst culdolaparoscopic appendectomies on three patients were reported by Tsin et al. in 2001 [16]. Prior to the transvaginal positioning of a 12 mm trocar, mini ­laparoscopy was performed and 5 mm and 3 mm trocars positioned in the left and right lower abdomen. The vaginal trocar was used for positioning the stapler and for extracting the appendix.
Netzhat et al. removed the appendixes of 42 patients by means of a transvaginally positioned stapler following laparoscopic or laparoscopically assisted vaginal hysterec­tomy. Recovery was also conducted transvaginally. In the histology of incidental appendectomies, endometriosis lesions were discovered in four cases and a carcinoid tumor in one case [17].
NOTES-related procedures
The difference between NOTES surgery and the operations described previously is, for one thing, that the translumenal path is the main route of access to the organ and that fl exible endoscopes are primarily used. Furthermore, the indication for surgery is the necessity of removing the acutely infl amed appendix. The currently possible translumenal access routes are the oral route, and thence through the gastric wall, and the transvaginal route. In principle, the transrectal route would also be possible, but on account of the major risk of
infection, there is as yet no clinical experience in respect of that route. Since the transvaginal access route was the easiest, the fi rst operations took place via that route.
Transvaginal appendectomy
Historically, the transvaginal route is not new, but the focus on the effector organs, and the instruments employed, have changed. This access route has long been tested in gynecol­ogy and safe decontamination is possible.
Various modifi cations of the procedure are possible in the performance of transvaginal appendectomy: pure NOTES surgery, fl exible hybrid surgery, i.e., with auxiliary abdomi­nal access via the umbilicus, and surgery using rigid instru­ments inserted into the vagina, which is also a hybrid technique. The fl exible hybrid technique can be divided into two sub -types: laparoscopically supported fl exible appen­dectomy and fl exibly assisted rigid preparation. For all oper­ations using a fl exible instrument, the use of a dual -channel device with a separate water jet channel is to be recom­mended. This has the advantage that when one working channel is in use, the other is available for suction, and the irrigation channel is completely separate. For pure NOTES procedures, the availability of CO
insuffl ation via one of the
2
working channels must also be ensured. In all cases, the Lloyd-Davis position was employed, with the surgeon stand­ing between the patient ’s legs. Also, in all the procedures, the vaginal incision was closed in the same way, namely by means of hand -sewn stitches. In the following, the technical procedures used in the individual variants are presented.
Pure NOTES appendectomy (Video 12.1)
This procedure corresponds to the original NOTES concept, but it is also the most diffi cult to perform, and with the cur­rently available instruments it is only possible in exceptional cases.
The abdominal cavity can be accessed via an open col­potomy, and it is conceivable that hydroscopic access after Watrelot et al. might also be possible [18]. In this procedure, NaCl solution is applied into the Douglas pouch by means of a transvaginal puncture in order to form an organ -free space by causing any loops in the small intestine to fl oat and thus to increase distance from the rectum. With the patient in the Trendelenburg position, a trocar is then introduced and after removal of the fl uid capnoperitoneum is induced.
After the colpotomy incision has been made and the endoscope inserted into the abdominal cavity, the capnoper­itoneum is initially established via a working channel. After the performance of a peritoneoscopy, the cecum is located and the appendix exposed and pulled forward using graspers (Figures 12.1 and 12.2). Now coagulation forceps can be used, starting with initial fenestration, to prepare the mesoappendix, starting from the base of the appendix. The arteria appendicularis is coagulated or sealed with surgical clips (Figures 12.3–12.6). Thanks to the high optical resolu-

tion, this procedure can be performed very precisely. Prepa­ration can be facilitated by harnessing the appendix with a second set of graspers. This, however, is not easy, because both instruments project from the endoscope, are located very close together and move simultaneously as the device is manipulated. A further limiting factor is the reduced maneuverability of the fl exible instruments, particularly in cases of severe infl ammation and adhesion of the mesoap-

After the base of the appendix has been exposed, ligation is per­formed using an endoloop and the appendix detached with scissors, the snare, or the needle -knife (Figures 12.8–12.11). The detached appendix can be recovered transvaginally as the instruments are withdrawn (Figure 12.12). This procedure is, however, only possible with low levels of

introduced. After inspection of the abdomen, the posterior vaginal vault is penetrated with the mandrin of a 12 mm trocar with the patient in anti -Trendelenburg position. The endoscope is then introduced via this opening and visualiza­tion is thereafter provided by this instrument. The appendix can then be pulled free and tensioned by 5 mm graspers introduced via the umbilical port (Figure 12.13). The prepa-

ration of the mesoappendix is conducted as described above (Figure 12.14–12.18). Subsequently, the base of the appen­dix is ligated using a snare introduced via the umbilicus and the appendix detached by means of laparoscopic scissors (Figures 12.19 and 12.20). In these two procedures endo­scopic graspers are used to tension the appendix. The speci­men is then recovered transvaginally.

Rigid transvaginal appendectomy, assisted by fl exible instruments (Video 12.3)
In this type of operation, a 12 mm trocar is introduced paral­lel to the endoscope in addition to the procedure described above (Figure 12.21). Preparation can be conducted through this using a rigid instrument and the detachment of the appendix performed with a stapler. Here, the endoscope is only used for visualization, irrigation, and suction and for occasional grasping maneuvers (Figures 12.22–12.26). This approach is particularly to be recommended in cases of severe infl ammation and diffi culty in ligating the base of the appendix.

In contrast to the procedure described above, the endoscope is here replaced by a rigid laparoscopic camera and the operation performed using only laparoscopic instruments as in culdolaparoscopy.
The fi rst transvaginal appendectomy was performed by our working group as a pure NOTES procedure in Septem­ber 2007 [19]. The patient was a 28 -year old woman with recurrent sub -acute appendix irritation. Peri -operative pro-

phylactic antibiotics were administered and after local disin­fection and the laying of a urine catheter, a conventional posterior colpotomy was performed, via which a single ­channel gastroscope (Olympus Germany GmbH, Hamburg, Germany) was then introduced into the abdominal cavity.

at a pressure of 10 mm Hg was pro-

has been demonstrated in several studies [20–22]. Prepara­tion was conducted using hot biopsy graspers and an IT knife. Between endoloops the appendix was detached using endoscopic scissors. The patient was discharged on the third postoperative day. Two weeks after surgery she began a suc­cessful two -handed Atlantic crossing in a sailing yacht.
Between October 2007 and February 2011, eleven further patients gave their consent to hybrid surgery under study conditions [23]. The operations were performed according to the hybrid procedure described above, using a dual-channel gastroscope (Karl Storz GmbH, Tuttlingen, Germany). The sterility of the gastroscope was achieved by

75.5 min, with a range of 40 –110 min. The intra -abdominal pressure build -up amounted to 10 –12 mm Hg. The age of the patients extended from 19 to 73 years. The BMI ranged from 21.05 to 31.1. All procedures were conducted with the administration of peri -operative prophylactic antibiotics. In
